>> Now we know how few gates it takes to do arithmetic, and understand that, in a fundamental sense, it's simple. There is no context in which arithmetic can be done, or understood, without a human mind, though. An ALU doesn't understand that it's adding two numbers anymore than a car understands that it's rolling down the highway. They're both still machines that do things that humans want them to do, for reasons that humans want them to do them. Bottom line: it's still the case that only humans can do arithmetic; whether by hand, or Pascaline, or by modern ALU, it makes no difference. Arithmetic is a human thing.
